A centralized gateway (CGW) can be provided to facilitate assistance through client devices in the network. The CGW and the client device can use a common protocol and a common interface to take actions related to assistance.

  The CGW can collect information from a first client device using a common protocol via a first radio access technology. The CGW can fuse the information collected from the first client device with information associated with the second client device. For example, information collected from a first client device can be combined with other information received from a second device, other devices, other networks, and the like. Based on the merged information, the CGW can determine an action to be performed by the first client device via the second radio access technology to provide assistance. The assistance can be a control function and / or a assistance service. The CGW can send instructions to the first client device to perform actions using a common protocol. For example, a first client device may be associated with a first network configured to operate using a first radio access technology, and the second client device is a second client device Associated with a second network configured to operate using a wireless access technology of: The instructions may instruct the first client device to activate the second radio access technology and communicate with the second client device via the second radio access technology and provide assistance. it can.

  Client devices can provide information to the CGW using a common protocol via a first radio access technology. For example, the client device may be associated with a network configured to operate using a first radio access technology. In addition, the client device attaches to the CGW and provides one or more of the radio access technology (s), operating mode information, location information, service / capability information, etc. supported by the client device can do. The client device can receive instructions from the CGW to perform actions and provide assistance across multiple networks via the second radio access technology. This instruction may be received using a common protocol via the first radio access technology. The client device can perform the action via the second radio access technology. For example, the client device can support another network configured to operate using a second radio access technology.

It should be understood that other embodiments may be used or modifications and additions may be made to the described embodiments.

  FIG. 1 illustrates a typical home network environment 100 with examples of these technologies. Access to content (e.g., web and video) is based on the homeowner's (one or more) internet protocol (IP) backhaul connections (e.g., digital subscriber line (DSL), cable, FTTH (fiber to the)). home), satellite, etc.) may be provided via a broadband modem. Mobile services (e.g., voice and data) are provided through cellular networks, e.g., via macrocells (if possible by coverage) or via femtocells. The femtocell can connect to the cellular network using the homeowner's IP backhaul.

  A wireless local area network (WLAN) access point (AP) that uses WIFI technology to provide data connectivity between PCs, laptops, and other networked devices (eg, printers and fax machines) Can do. Bluetooth can also be used for point-to-point technologies (eg, between camera and PC, between keyboard / mouse and PC, between mobile phone and wireless headset). High throughput point-to-point links can also be used. A typical use case for such high speed links is for replacement of video distribution cables (eg, set top box (STB) to high definition television (HDTV)). For example, wireless sensor networks for monitoring heating, ventilation and air conditioning (HVAC) systems, lighting systems may be used.

  Table 1 lists some features of each radio access technology. Table 1 is a high-level comparison of specific technologies expressed in four main criteria (range, peak throughput, channel bandwidth, and operating bandwidth). The channel bandwidth in Table 1 indicates the spectrum occupied by a typical transmission. Specific details about each technology can be found in the relevant applicable standards.

  Domestic technology can be evaluated as follows. That is: 1) Device range can be highly dependent on specific technology 2) Some technologies that use unlicensed spectrum operate in the 2.4 GHz band 3) Higher data throughput May rely on the use of 5 GHz and 60 GHz bands (the latter may be useful for transmitting video traffic), 4) Some technologies may require manual intervention before network formation There are (eg, channel selection for WIFI networks), 5) For most technologies, device discovery may allow periodic beacons or probe / request mechanisms.

  Typical homes include cordless phones (which may have 5-10 MHz bandwidth), baby monitors, microwave ovens (some older devices may span the entire 2.4 GHz band, to name a few. There may be several sources of interference, including wireless video cameras, game controllers, and fluorescent lights. Each technology at home or office can be a closed network. There may be no harmonization between these network technologies. These networks may rely on their own procedures for network formation, network discovery, service discovery, and interference management. This can be inefficient.

  A “wireless transmit / receive unit (WTRU)” may include any electronic device capable of transmitting and / or receiving data via one or more wireless interfaces. The term “WTRU” includes but is not limited to within a user equipment (UE), mobile station, fixed or mobile subscriber unit, pager, cellular telephone, personal digital assistant (PDA), computer, or wireless environment.

Can include logical or physical entities.

  Various home / office network technologies can be referred to as capillary networks. Capillary networks can be supported, thereby improving performance within the capillary network. A centralized gateway (CGW) is disclosed that can facilitate such assistance, for example via client devices in a capillary network. A CGW may be referred to as a convergence gateway, centralized entity, central entity, and so on. A client device may be referred to as a client.

  FIG. 2 shows an exemplary CGW 210 that can communicate with the capillary network 220 and the external network 230. CGW 210 may provide access to external network 230 (eg, cellular, internet, etc.). The CGW 210 can communicate with the capillary network 220 via a common interface, such as a logical “A” interface 215 that provides signaling support for a set of control procedures managed by a “common logical A protocol”. The CGW 210 can collect information from the capillary network 220 and / or the external network 230 and fuse the information. The CGW 210 can use the merged information in supporting the capillary network 220 and their devices. Assistance can include, without limitation, one or more of the following: assisting, assistant service (s), network control, harmonizing, routing, measurement, service, etc. Or you can call it like that. Assistance can include controlling one capillary network to assist another capillary network.

  At least one device in the capillary network may be capable of communicating via a logical A interface. CGW, for example, 1) Coordination of spectrum usage (interference management), 2) Node discovery support, 3) Inter-capillary network communication, 4) Intra-capillary network communication, 5) Assisted service discovery (eg, continuation for peer gaming) Broadcast session), 6) assisted load management, 7) opportunistic assisted setup via mobile devices, 8) assisted location mapping, etc.

  Assistant services refer to services that can rely on fused and / or raw data stored in a centralized gateway (CGW) to assist and coordinate the capillary network. The assistant service can reside both on the CGW and the attached device. The assistant service can rely on common logic A protocol procedures for communication between the CGW and the attached device.

  The CGW can provide support and harmonize among various capillary networks based on fusion information and raw information from capillary networks and external networks. The CGW may execute a common logic A protocol and communicate with client devices in the capillary network using a logic A interface. Furthermore, the CGW can execute an assistant service that uses the merged data and raw data.

  A capillary network (CN) can refer to a network managed directly or indirectly by the CGW. Capillary networks can include ZigBee networks, WIFI networks, Bluetooth networks, direct links, infrastructure networks, and the like. An attached device (AD) can refer to a device that is attached to or known to the CGW. The AD may be synchronized with the CGW and can receive transmitted control information. AD can show capability to CGW.

  Physical location can refer to the location of the device in physical space (eg, XYZ coordinates, room, etc.). The wireless location can refer to the location of the device with respect to being able to communicate with the CGW, for example. The coverage zone can refer to the cover of the CGW. Coverage zones apply to office and commercial environments.

  FIG. 3 shows an exemplary central gateway CGW 310 connected to a plurality of capillary networks (capillary network A 320, capillary network B 322, and capillary network C 324) and external network 330. Information can be collected from these capillary networks and external network 330 and merged within CGW 310. The CGW 310 uses the merged information 1) to provide support services and network control to one of the capillary networks to which this central entity is connected (eg, radio frequency (RF from the capillary network A320) ) Gather characteristics such as measurements and location information and fuse within the central entity to support the capillary network B322) 2) Control one of the capillary networks in supporting another capillary network (For example, the location and device capabilities of capillary network A 320 and capillary network B 322 are collected and fused within a central entity, and the CGW controls the devices in capillary network A 320 and capillary network B 32 Can such support can be) things.

  Information collection from the capillary network, as well as signaling to convey control information or support information to the plurality of capillary networks, may be enabled by a common logical interface, which may be referred to as a logical A interface or a common logical A interface. it can. This interface can link a common logical A protocol that can reside on the CGW 310 and client devices in the capillary network. In CGW 310, the common logical A protocol can be an upper layer 311 that is common to multiple radio access technologies (RATs) (X, Y, and Z), allowing communication with multiple capillary networks. it can. The logical A interface requires modification of the MAC and PHY layers of the RAT that supports the logical A interface.

  The CGW can support and harmonize capillary networks and provide the capability for inter-capillary network routing. The CGW can implement communication with an external network (eg, cellular, Internet, etc.) via, for example, a wireless cellular interface, a home IP connection (eg, via DSL, cable, FTTH), a satellite connection, etc. The CGW may be an extended wireless LAN access point, an advanced H (e) NB, a convergence device with both functions (and possibly other functions), and so on. A mobile phone can behave as a CGW if it has a multi-RAT function, for example.

  Each device in the capillary network may need to communicate with the CGW via a physical link. A device that communicates with the CGW can cooperate with the CGW and can be referred to as an attached device (AD). Communication can be via a logical A interface that can provide synchronization, control, data plane functions, and the like. The control information can provide signaling between the capillary network device and the CGW, and can enable assistance and coordination managed by the CGW.

  These functions may be performed via a dedicated channel, which may be a separate channel for each AD, or via a shared channel, eg using a carrier sense multiple access / collision avoidance scheme (CSMA / CA). it can. Synchronization can provide the capillary network device with reference timing, instructions on where to find control information, and the like. The control information can provide signaling between certain capillary network devices and the CGW, and can enable assistance and coordination managed by the CGW.

  The logic A interface can be implemented using an air interface that can be optimized for a particular application and condition (eg, home, office, industry, etc.). It can also be implemented with a logical A protocol that can be a common layer on top of multiple existing RATs. The logical A interface may be based on any other technology. For example, if the CGW has H (e) NB functionality and WIFI, the logical A protocol may be on top of the Uu interface (Advanced H (e) NB interface) and the 802.11 interface.

  The AD can have at least one RAT that can be capable of communicating with the CGW. The AD has a common logical A protocol, which may be on top of a supported RAT and manages the logical A interface procedure. A client version of the assistant service may exist in the AD.

  The CGW and client device can collect and format information from the capillary network via multiple RATs using a common protocol such as the logical A protocol. This can allow for standards-based collection across multiple RATs. For example, measurements collected using existing standards-based techniques can be sent via RAT X for a given client via a format common to each RAT. The common logic A protocol can allow decisions based on merged data from multiple capillary networks to be sent to a particular RAT client, enabling new procedures for multi-RAT clients Can do.

  When a device joins the network, wants to communicate with the CGW to use the services provided by the CGW, and is capable of multi-RAT operation, the device can be Can be used to attach to the CGW and inform the CGW about its multi-RAT capabilities and other capabilities.

  FIG. 4 illustrates an exemplary attach procedure. In 1, the client 420 can discover the network (CGW 410) by obtaining synchronization and control information broadcast by the network using a given RAT technology (eg, RAT Y). The client 420 can use any of the RAT technologies that can be supported, in this case RAT X, RAT Y, RAT Z. 2, client 420 can attach to CGW 410 using RAT Y. For example, the client 420 can attach to the network using RAT Y and obtain a network address, a MAC address, and the like. 3, client 420 can send an attach request via the common logical A protocol using the most recently activated RAT Y. The attach request can include the multi-RAT function of the client 420. This allows CGW 410 to trigger another RAT activation at 4 or later. The attach procedure may include capability information related to multi-RAT service support.

  The attach request may be: a) each RAT supported by the client 420, b) what band is supported for each RAT, regardless of whether the device is a mode 1 device, a mode II device, or a sensing-only device. c) For each RAT, which other RATs can be supported simultaneously (eg, GSM RAT can support Bluetooth but cannot support WCDMA or LTE), d) For each RAT , Whether or not the RAT is active, e) a location tracking function, or f) a TVWS function. The attach request may include information regarding services provided by the client 420 (eg, gaming, printing, storage, physical location, etc.).

  At 4, the CGW 410 can send an attach response, which can indicate whether the attach request has been accepted. This procedure can be supplemented with authentication procedures and security procedures. The attach response can include a command to activate another RAT as an alternative or supplemental RAT based on the capabilities provided by the attach request. This command may include the same information carried in the secondary RAT activation request.

  A common logic A protocol in a CGW, such as CGW 410, can maintain a state machine for each client to maintain knowledge of which RAT is active at a given time, along with its operating bandwidth. A common logical A protocol at a client device, such as client 420, can maintain a state machine for that network to maintain knowledge of which RATs are active in its vicinity at a given time.

  The logical A protocol in the CGW can broadcast available RATs and associated bands supported by the network. This information can be signaled via any available RAT, eg, periodically. This allows the client to autonomously activate another RAT without having to discover other available RATs.

  Activation of a secondary RAT for a given device already operating in the primary RAT can be initiated by the device itself or by the CGW. The device can be triggered by a user decision or initiated based on a device application decision (eg, in a cell phone operating on a cellular network, the user can enable Bluetooth RAT, Transfer file to PC). The CGW can initiate the network device and command the network device to activate the secondary RAT in the context of network assistance. For example, the CGW can enable the secondary RAT and command the device to perform sensing to assist another network operating primarily in the secondary RAT. The CGW can instruct the two devices to make the RAT available to set up a direct link between these two devices with a secondary RAT (eg, the CGW can The 802.11n / TVWS direct link is coordinated with the setup box attached to the CGW mainly in the 802.11 / ISM band).

  Regardless of activation initiated by the device or activation initiated by the CGW, the common logical A protocol can define a procedure to support secondary RAT activation. These procedures may include the device sending a secondary RAT activation indication signal to the CGW, which signal 1) the nature of the indication (eg, the device notifying the CGW about the device's decision, RAT Device requesting assistance from CGW to provide designation and / or RAT configuration, etc.) 2) RAT to be activated, or 3) Including used bandwidth, channel information, power settings, antenna settings, etc. One or more of the possible RAT configurations can be included. If the nature of the indication is to request assistance, the CGW can return a secondary RAT activation response with the requested information. At the end of the RAT operation, a secondary RAT deactivation indication and response can be sent.

  The common logical A protocol may define a procedure for supporting secondary RAT activation, which includes sending a CGW a secondary RAT activation request signal to a device or set of devices. be able to. Prior to sending this request, the common logical A protocol at the CGW can ascertain the capabilities of the device and whether its RAT is already active, for example by using a state machine for each device. This request may include one or more of the following. That is, 1) causes of activation such as sensing, direct link setup, location tracking, 2) RAT to be activated, 3) RAT configuration that can include bandwidth used, channel information, power settings, antenna settings, etc. (eg, Bluetooth) When activating RAT, the device is instructed to channel hopping sequence), this function can be used to speed up capillary network discovery, 4) time to activate, 5) device role (eg , CGW may request device to act as AP or client when enabling WIFI RAT), 6) Peer that may be applicable when direct link setup or device location tracking is used Device identification or 7) Activation for sensing , The CGW may provide measurement configuration information (eg, which events are monitored, when measurement reports are returned (regular or triggered), etc.).

  The device can accept or reject the activation request and can send a secondary RAT activation confirmation. When rejecting a request, a reason can be included. A secondary RAT deactivation request and confirmation is required to terminate the RAT operation. The common logic A protocol at the CGW can dynamically maintain a state machine for each client upon RAT activation or deactivation.

  FIG. 5 illustrates an exemplary coordination of a direct link setup between two client devices. In FIG. 5, a direct link setup on the secondary RAT X is made between two devices already attached to the CGW 510 via different primary RATs, namely RAT Y and RAT Z, ie, client A 520 and client B 530, respectively. Can be adjusted.

  At A, CGW 510 may instruct client A 520 to activate RAT X and establish communication with client 530. At B, CGW 510 can instruct client B 530 to activate RAT X and establish communication with client A 520. In C, client A 520 and client B 530 can activate RAT X. At D, client A 520 can cooperate with client B 530 using RAT X.

  Several procedures that can change the mode of operation of the entire capillary network or of a particular capillary network device can be enabled by the common logic A protocol. The term “mode of operation” refers to 1) operating frequency band, 2) operating frequency channel, 3) transmission related parameters that can include modulation, coding, power, and directivity, 4) capillary network media access configuration parameters, Or 5) For example, one or more of the client roles (eg router, end device, coordinator, etc.) of the device where the WIFI station may be asked to act as an access point for load balancing or range expansion Can point. The mode of operation can be changed based on the merged data or assistant service logic available at CGW 510. This decision is sent to the target attached device, which is then responsible for initiating the change of operating mode.

  In FIG. 6, an exemplary frequency band change is shown. This is a procedure that allows the CGW to use the merged data and determine that the capillary network can change the operating frequency band. It should be understood that similar mechanisms can be used for other procedures, which can include using different signaling.

  Referring to FIG. 6, at 1, the CGW 610 determines that the frequency band for the capillary network A 630 may need to be changed based on the merged data information. The decision algorithm can rely on fused information regarding one or more of device location, capillary network load, interference level, or spectrum availability (eg, white space). For example, the support service in CGW 610 may determine that the interference level at the current operating frequency is high and that a band change may be required to maintain adequate quality of service for capillary network A630. In another example, an assistant service in CGW 610 can determine that the current bandwidth is experiencing congestion and can request a bandwidth change for load balancing.

  2, CGW 610 can send a control message to the attached client device (client A 620) in capillary network A 630, requesting a change in operating band. This message includes 1) new operating band and frequency, 2) device transmission related parameters (eg, modulation, coding, Tx power, etc.), 3) time related parameters (eg, when changes take effect 4) Result of failure (for example, what to do if the capillary network is unable to perform a bandwidth change, for example, stop operation on the capillary network) Include one or more of: 5) the type of result to return to succeed) or 5) may be instructed to continue with the current band using different transmission parameters Can do.

  3, client A 620 can initiate a capillary network protocol via RAT X to change the operating band. For example, if the capillary network is an 802.15.4 ZigBee WPAN network, the attached device, ie client A 620, can communicate with the WPAN network manager and request a channel change. If this operation is successful, the capillary network A 630 can change the operation band at 4. 5, client A 620 can respond with an indication of successful operation mode change. Otherwise, client A can respond with an operational mode change failure indication.

  The logical A protocol can include one or more of the procedures described in Table 2. Secondary RAT activation and operational mode change may use one or more of the procedures described in Table 2.

  FIG. 7 shows an exemplary system operation diagram. CGW 710 may collect information (eg, RF measurements, network operational measurements, traffic rates, loads, device locations, device capabilities, etc.) from capillary network 720 and from external network 730 via a logical A interface. it can. This information may be collected during device attachment to the CGW. This information may be collected during ongoing device operation, for example when there is a change or periodically. In order for the CGW 710 to collect information, the CGW 710 can control and configure the devices of the capillary network 720 to report the information. The CGW 710 can create a specific database 760 for each network (eg, capillary network and external network) from the collected information. CGW 710 can execute a set of data fusion algorithms 765. The data fusion algorithm can fuse information collected from the capillary network 720 and / or the external network 730. CGW 710 may be dynamically updated and configured with an information fusion algorithm. The example information fusion database 770 can include one or more of, but not limited to, a device location map, a service / capability repository, a capillary network coverage map, or a frequency availability map.

  The CGW 710 can collect and fuse device location information into a device location map, eg, from one or more capillary networks. The fused information can be a map of the location of the multi-network attached device, which can be a physical location or a wireless location. The fused information may provide one or more of assistant services, such as assistant service 780, that may be used by CGW 710 and include any of the assistance disclosed herein. For example, the assistant service 780 can provide emergency location services in the home or office, device maintenance (eg, knowing the location of a failed mobile device), coordination of spectrum usage, node discovery assistance, inter-capillary network communication, assisted One or more of service discovery, assisted load management, setup of opportunistic assistance via mobile devices, assisted location mapping, etc. can be included. This fused data can assist in spectrum management. The CGW 710 can make spectrum management decisions based on the density of the attached device, thereby avoiding assigning heavily used spectra at certain locations.

  The CGW 710 can collect device capability information and service information from the capillary network 720 and merge it into a service / capacity repository. Capability information includes radio access capabilities (eg, supported technologies, radio bands, transmit / receive bit rates, transmit power limits, etc.), as well as power sources (eg, batteries and commercial power sources), available power (eg, battery operated devices) ), Storage functions, usable storage, and other information that handles other physical attributes. The service information can include an indication of ongoing or potential services that can be provided by devices in the capillary network. Through the use of proxy device attach procedures, the CGW 710 can track service / capability information for devices that do not communicate directly with the CGW 710 (eg, those devices do not have an A interface). The proxy device can relay service / capability information to the CGW 710. This information may be merged with other types of merged information, including device location maps.

  The fused information can be stored in the information fusion database 770. Information fusion database 770 may be updated dynamically and periodically, for example, by execution of data fusion algorithm 765. New types of information fusion can be added to the information fusion database.

  The CGW 710 can store a set of assistant services 780 to control, coordinate, and support the capillary network 720. The assistant service 780 can use the collected raw information specific to each network, such as the merged information as well as the information available in a particular database 760. Various assistant services can be defined. CGW 710 may be dynamically updated and configured with new assistant services. The CGW 710 can be controlled and supported by directly controlling one capillary network. The CGW 710 can control one of the capillary networks in supporting and controlling another capillary network.

  This system architecture enables various assistant services 780. Each assistant service provides an information fusion database 770 and an individual capillary network database to directly support the capillary network and / or to control one of the capillary networks in supporting another capillary network. Can be used. The CGW 710 may request the capillary network A 721 or a specific device belonging to the capillary network A 721 to sense the operating channel with a specific sensing algorithm applicable to the capillary network B 722 in order to support the capillary network B 722. it can. In the situation of low power, low complexity devices such as ZigBee / 802.15.4 capillary networks, the device spends most of its time in sleep mode to conserve power and has limited sensing capabilities. ing. These types of networks do not perform aggressive RF measurements. These networks are subject to dynamic interference. In that situation, a juxtaposed capillary network, such as a WIFI network, ie capillary network A721, performs the sensing measurement and supports the ZigBee network.

  The CGW 710 can collect device location information and ZigBee network and WIFI network operating characteristics, which can include ZigBee network operating channels. The CGW 710 can then instruct the WIFI device to perform periodic RF measurements on the ZigBee operating channel with a specific sensing algorithm applicable to the ZigBee network. These RF measurements can be collected periodically by CGW 710. The CGW 710 can periodically blend the RF measurements for each WIFI device with the WIFI device location map as well as the ZigBee device location map to detect that high interference is occurring on the ZigBee channel. Consideration of RF measurements may be limited to WIFI devices juxtaposed with ZigBee devices. After the interference is detected, the CGW 710 notifies the ZigBee network and / or instructs the device attached to the CGW 710 via the ZigBee AD, the logical A protocol, to initiate a network channel switch. The ZigBee network can be controlled.

  The CGW 710 can instruct the WIFI device to monitor the available alternate channels for the ZigBee network. After high interference is detected, the CGW 710 can control the ZigBee network to switch the channel to its valid alternate channel. Service discontinuities that may occur as a result of interference can be reduced in a ZigBee network.

  The CGW 710 can set up and control proxy devices with multi-RAT functionality by providing opportunistic network repair assistance for a given capillary network. When CGW 710 communicates with AD from multiple technologies, it can ask the device to assist in the operation of one or more capillary networks. This assistance can be opportunistic in that there is no guarantee that AD is within the scope of the target capillary network. The final decision on whether to support is left to AD. For example, the AD determines not to provide opportunistic assistance to conserve battery power.

  Still referring to FIG. 7, at 1, the CGW 710 can collect information about the capillary network 720 and the external network 730 in terms of their connectivity, their location, their RAT capabilities, and so on. Information is collected and fused as indicated at 2, 3, 4. The CGW 710 executes the application at 5 and determines the assistant service required, for example, a device in a given capillary network (eg, capillary network A 721) is not connected to the capillary network (this device is a singleton device) (Which can be referred to as a singleton device or node). Singleton detection applications may also be triggered by notifying CGW 710 of any of the devices in the capillary network. 6, the CGW 710 can support the capillary network 720.

  The network repair support application can be triggered by the CGW 710. CGW 710 uses information fusion database 770 to provide a device with multi-RAT capability (eg, a device with RAT capability Y assuming that capillary network A 721 uses RAT Y) near the predicted location of the singleton node. ) Can be identified. This device can be referred to as a proxy healing device. Since this device has not activated the RAT used by Capillary Network A, CGW 710 will probably need to use the device's currently active RAT (eg, RAT X) for the proxy repair device. Can be notified. This can trigger RAT Y activation, which is used by the singleton node. The proxy repair device can communicate with a singleton node, or possibly an adjacent node, and reconnect the singleton node with its neighbors. For example, capillary network A 721 can be based on Bluetooth technology (eg, Bluetooth can support RAT Y). In a scatternet, the Bluetooth node can be a master node or a slave node. A master node cannot connect to another master node, thus creating a bottleneck in the capillary network. The proxy repair device can interact with these nodes and force them to change their roles, thus permanently repairing the nodes.

  The proxy repair device can broadcast information to speed up network formation and network participation by communicating with a legacy ZigBee network that cannot be attached to the CGW 710. In such cases, the mobile acts as a relay to control messages to / from the capillary network.

  By collecting information about the capillary network and signaling this information to the CGW 710, network repair assistance can be provided. This information can be “filtered” at the repair device and an indication can be sent to the CGW 710 based on the filtered data and based on some threshold. The AD and capillary network are not necessarily limited to those described.

  By way of example, the attached device can be a smartphone attached to the CGW, and can include an indication to support ZigBee in its capability information. The CGW can then request that the attached device support the ZigBee network. This support includes: 1) Extending the reach of the CGW by sending synchronization / control channel information as a proxy for the CGW, 2) Connecting to a ZigBee capillary network and going to a temporary router or CGW in that capillary network One or more of acting as a gateway.

  A proxy tracking service can be provided. One or more devices that are currently inactive in the capillary network A 721 can be used to track the position of devices that belong to the capillary network A 721 and whose position is unknown or does not have a position tracking function. Request to track a device with an unknown location by first identifying one or more devices with a known or tracked location function and a RAT function that matches a device with an unknown location Can be processed by the CGW 710. The identified device can activate a matching RAT, can initiate a scan, and can actively or passively detect the presence of an unknown device. If a device finds a device with an unknown location, it can notify the CGW 710 and provide additional observation characteristics such as signal strength. For example, there is a request to find a Bluetooth-enabled camera, requesting a smartphone spread throughout the house, or other consumer electronics device with a known location, to activate the Bluetooth radio and scan for a camera that uses Bluetooth technology can do.

  Capability network service discovery support can be provided. Using the fused information, including information about available / ongoing services at multiple RATs in the capillary network, the CGW 710 can identify a device (or multiple devices) from the capillary network to a specific RAT. Can be made available and helped to use the service. This can be useful for sharing peer-to-peer applications (eg, gaming). For example, when entering home or after turning on a smartphone, the device can attach to the CGW 710 via a common logic A interface (eg, WIFI). When attached, the smartphone can notify the CGW 710 about its service preferences and its capabilities. The CGW 710 merges and uses the service / capability repository with the device location map in the information fusion database 770 and provides a directed response to the smartphone that provides nearby services based on device preferences / capabilities. Issue. The smartphone can be made aware of the provision of the service via broadcast information by the CGW 710. After the user selects an ongoing service, such as a game, the CGW 710 can assist the smartphone at the location where the game is taking place and provide directions and / or distances. The CGW 710 can provide a location map in a physical home layout. While the user is moving to a location where a game is being played on the Bluetooth network (eg, a room in a home), the CGW 710 enables the smartphone to use its Bluetooth RAT, which is disabled by default. Can be configured with a channel to be used and a channel hopping sequence. Therefore, the smartphone can cooperate with the Bluetooth network at high speed, which can provide the user with an experience of starting the game at high speed.

  Capillary network optimization support service uses the fused and raw data by the CGW to optimize the performance of the capillary network (eg, by maximizing throughput, minimizing delay, etc.) Can be a service that can help. For example, many capillary networks can use a form of carrier sensing (eg, CSMA / CA) as part of the media access protocol. If there is a centralized entity such as a CGW, it can be used to support the medium access control (MAC) algorithm in several ways, which are 1) frame / slot to allow slot CSMA Providing a structure, 2) broadcasting a jam signal to the attached device where the collision is occurring, which is a request-to-send (RTS) / clear-to-send send: CTS) can eliminate the need for transmissions, 3) CGW uses AD location knowledge and service profile and adjusts parameters to maximize throughput or minimize interference Signaling / broadcasting dynamic MAC parameters if possible (For example, in 802.11, this may include an interframe interval parameter, a random backoff parameter after sensing a busy channel), or 4) the CGW manages the capacity request from the AD and only Basic CSMA by reserving a portion of spectrum resources for demand allocation based access control where capacity can be allocated based on any number of metrics including but not limited to fairness and traffic priority One or more of the enhancements to the / CA algorithm can be included.

  In addition, an assistant service can provide load management within the capillary network. For example, the CGW can decide to rearrange the capillary network. The CGW can divide the capillary network into two or more smaller capillary networks and decide to implement inter-capillary network communication between those networks. The throughput in each of the divided networks can then be maximized individually. This requires the CGW to be aware of the load in the capillary network (eg, routing congestion, delay statistics, throughput statistics, etc.). The CGW can instruct certain devices to change their parent router to another lighter router.

  The interference management assistance service uses the merged information about measured interference, device location, and device capabilities and requests the device to use a directed antenna, thereby directing energy to the desired receiver. , Away from other devices sharing the same bandwidth. The assistant service can provide the necessary information (eg, location, transmit power, etc.) to the device through broadcast information carried via the common logic A interface. The common logical A protocol in these devices can interpret the broadcast information and autonomously determine the direction of transmission.

  The interference management assistant service can provide time sharing of frequency channels. The CGW can coordinate time sharing of frequency channels across K capillary networks. The CGW can provide a usage schedule for these K capillary networks, and the common logic A protocol in the attached device can control the capillary network transmission based on this schedule.

  The interference management assistant service can assist in spectrum / interference management. The interference management assistant service is a centralized spectrum manager entity (via cellular networks and / or the Internet) that can reserve or allocate spectrum across multiple bands for home use that is of “high quality” (eg, low interference). And reachable). The spectrum manager can dynamically allocate spectrum based on requests from the CGW. The spectrum manager may make allocation and reassignment decisions based on other metrics, received measurement information from other CGWs, white space usage, and the like.

  After the spectrum is assigned to the CGW, the CGW can be responsible for managing the spectrum at home. For example, the CGW may decide to assign frequency channels to individual capillary networks based on received requests. The allocation size and frequency band can be a function of the traffic carried on the capillary network.

  The CGW uses device location information and / or the physical layout of the coverage zone and requires the device to use a directed antenna, thereby directing energy to the desired receiver and sharing the same band. Can be separated from other devices. The CGW can provide the necessary information (eg, location, transmit power, etc.) to the device and allow the device to autonomously determine the direction of transmission.

  The CGW can also control interference by limiting the transmission power of devices in the capillary network. The CGW can set the initial transmit power of the AD based on an open loop technique and then dynamically change this limit as the interference condition changes. The CGW can limit the minimum transmit power of the AD, for example, to ensure coverage in the capillary network.

  The session transfer support service can use the merged data and allow the CGW to control session transfer between devices. For example, a video session can be transferred from a smartphone to an HDTV. The session transfer assistance service can use the location map, capability map, and fused load / interference information to select a device (eg, a target device) to which the session is to be transferred. The CGW pages the target device, sets up a broadband modem (or other device that receives content) and a home route from the target device, reformats the data to meet the target device's service display requirements, Responsible for dismantling links to smartphones.

  FIG. 8 shows an exemplary client protocol stack within client device 820. In order to support the concept of CGW network assistance, client devices require two types of entities. First, the client logical A protocol 830 is required to implement the various procedures of the logical A interface, including: a) device attachment to the CGW, and service / capability repository in the information fusion database. Providing services / capabilities of devices that can be buried, b) measurement configurations and reports, c) if, for example, the CGW can activate the Bluetooth RAT of the smartphone and participate in ongoing games in the Bluetooth network, RAT activation / deactivation, or d) Capability where the Bluetooth RAT used or activated in the Capillary Network Sensing Assistance Service to switch channels in networks experiencing high interference is configured with channel information. One or more of channel configuration / reconfiguration used in the library network service discovery support service may be included. Second, one or more client assistant applications 840 can interact with the CGW service to enable CGW assistance. Client device 820 may be dynamically updated and configured with a new client assistant application 840. An example of a client assistant application is shown in a capillary network service discovery support service. When the CGW notifies the device about available games, the user can select a game via a client assistant application having a user interface. A client assistant application having a user interface can display a location map of the location where the game is played to the user.
